IMPROVED APPARATUS r03 FEEDING SGREW-BLANKS.

My: Sttehultniemt n in time game one ant making not at it: same.

TQ-ALL WHOM IT MAY ooncnnm Be it known that I, ELIJAH S. Planes, of Hartford, in tho'county of Hartford, and State of Connecticut, have invented a new and useful Improvement in Feeding Screw-Blanks or other similar-articles; -and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon.

Figure 8ll0\ YS "a front viewof a hopper and trough for feeding screw-blanks into a machine, with my,- improvemen't attached.

FignrcII shows a top view oi the same.

Figure III is a section through the middle of the belt and pulleys shown in Fig. I.

Figure 1V is a section through the middlco f the belt and pulleys shown in Fig. II.

FigureV shows a perspective view of my improvement as applied to the hopper of 'a screw-machine, together with sections of. two forms of roller. I

Like letters in the several figures indicate likaparts.

My invention consists in attaching to some part of tho'boppcr or'feeding-trough of a machine for performing some operation upon scrcw-bianks Q1.0ther similar articles, a puileyor roller, having an uneven -or flat sided surface, running against a belt, so that a vibratory motion is given to the several parts of the feeding "mechanism, whereby the blanks are jarred and shaken down from the hopper to the machine where they are to be operated upon.

A is the hopper, placcll'at a slight inclination,.into which the blanks are put.

13 is an inclined trough, of the usual construction, for conveying the blanks to. the machine.

Cl is a roller or pulley, attached to the feeding-trough, for giving the vibratory or jarring motion to thi feeding -apparatns. It is shown in Figs. Iand III of a polygonal form, and in Figs. Hand IV of a circular form, with raised ridges, made of wire, bent into the foi'ni of a staple, andthe ends driven into, the roller.

Any form of roller can be used, the surface of which is sufliciently uneven to give .a proper vibration to the feeding-apparatus. .This roller cnni be attached to any part-of the hopper or feeding-apparatus that may be most convenient for communicating \vith one of the belts of the machine.

D is abclt, which presses against therollcr O with snfiicient force, to communicate to it a rolling motion; This belt may be one of the ordinary belts of the'machine to which the feeding-apparatus is attached, or a belt especially for the 'purposcdcscribcd, in which case it might pass around the roller or pulley G. I

E is a pulley upon the machine, around ivhich the bolt D passes, in thearrnngement shown in the drawings.

The operation of my invention is as follows:

The hopper lhbeing filled with blanks, and motion given to the belt D, t'ne rollcr C'rolls upon thebclt in such a manner as to give a vibratory motion to all thc parts of the feeding-apparatus, and. thereby shakes or jars the blanks. so that they gradnally'pass down theslightly-inclined surface of the bottom of the hopper A, anddrop, at a nearly uniform rate, into thofecding-trough'B, the rapidity oi their passing from the hopper being regulated by theinclinati'on of the bottom of the hopper A. The blanks are caught by thetrough B, andfall into the groovejn a single'line, in the usual manner, which operation, as well as their passage through the trough, is assisted and. rendered more-certain in its action by the jarring motion given by the roller C,-

What I claim as my. invention, and desire tosccurc by Letters Patent, its-- The combination of theroller-Cand belt D with the hopper and trough A B, when constructed and-arranged substantially as herein described. I
